Answer:
11.3cm = RC
Step-by-step explanation:
We can find the radius by using Pythagorean theorem and finding RC
a^2 + b^2 = c^2
RQ^2 + QC^2 = RC^2
We are given QC = 8
QC is the perpendicular bisector of PR so QR is 1/2 PR
QR = 1/2 (16) = 8
RQ^2 + QC^2 = RC^2
8^2 + 8^2 = RC^2
64+64 = RC^2
128 = RC^2
Take the square root of each side
sqrt(128) = sqrt(RC^2)
11.3137 = RC
Rounding to the nearest tenth
11.3cm = RC
